a) 12hm-3200cm+730= ? M

B)130hm+12000m-800dm=? Km

C) 13000mm+79hm-480dm=? M

D)32km+45hm-700m=? Dam

Answer 1

a)

12 hm - 3 200 cm + 730 dm = ? m

= 1 200 m - 32 m + 73 m =

= 1 168 m + 73 m =

= 1 241 m

b)

130 hm + 12 000 m - 800 dam =? km

= 13 km + 12 km - 8 km =

= 25 km - 8 km =

= 17 km

c)

13 000 mm + 79 hm - 480 dm =? m

= 13 m + 7 900 m - 48 m =

= 7 913 m - 48 m =

= 7 865 m

d)

32 km + 45 hm - 700 m =? dam

= 3 200 dam + 450 dam - 70 dam =

= 3 650 dam - 70 dam =

= 3 580 dam
